Seems like this is worth a look if you're doing any work in oracle.
tightly integrated "Add-in" for Visual Studio .NET that brings the power of the Oracle Database to .NET developers!
Use the Oracle Explorer to browse your Oracle schema, launch one of the many powerful designers and wizards to create and alter schema objects, and drag and drop schema objects onto your form to automatically generate code.
There's also a PL/SQL editor and integrated context sensitive online help, including the Oracle SQL and PL/SQL Users Guides. And with the Oracle Data Window you won't have to leave the Visual Studio environment for routine database tasks like inserting and updating Oracle data or testing stored procedures! For the developer that requires maximum flexibility, there's also a SQL Query Window for executing any SQL or SQL script you choose.
The only thing missing on the site (and people, this is important!) is screenshots! You can get away with much but lack of screenshots kills the story. Just a small FYI.
